The power
factor controller is working together with the capacitors and reactors (in
detuned filter cabinets), which is the key component of the automatic power
factor correction system. It is in fact the "intelligent" element,
responsible for the verification of the power factor of the load, in function
of which controls the switching on and off of the capacitors batteries in order
to maintain the power factor of the system beyond the target.

The reactive
power regulators RPC are designed to provide the desired power factor while minimizing
the wearing on the banks of capacitors, accurate and reliable in measuring and
control functions are simple and intuitive in installation and consultation.
The flexibility of ICAR regulators allows you to modify all the parameters to
customize its operation to fit the actual characteristics of the system to be
corrected (threshold power factor, sensitivity of step switching, reconnecting
time of the steps, presence of photovoltaics, etc.).

ICAR provides several types of power
factor controllers due to number of steps and existence of harmonic distortion
and other specifications:

5LSA/
7LSA reactive power regulators equip MicroMatic, Minimatic, MIDImatic,
automatic power factor correction systems. They are managed by a microprocessor
and offer many features while maintaining a simple way of consultation, either
locally or from a PC via RS232 serial port to which they are fitted as
standard.

They
offer a flexibility of use, are in fact able to adjust the power factor between
0,8 inductive to 0,8 capacitive, and to operate in cogeneration plants; offer
standard temperature control and the ability to set one of available output
relays for activating visual alarms/sound at distance.

The
RPC 5LSA 7LSA regulators can operate in automatic or manual mode.

In
the first case acting in complete autonomy switching on and disconnecting the
steps available until reaching the desired power factor; in the second case
will be the operator to force the switching and disconnection of the steps: the
regulator, however, will monitor operations to prevent potential damage to the
capacitors (such as verifying compliance with the discharge times before a new switching).
